The FirmLoader is an IDA plugin that allows to automatically identify parts of the memory for the firmware images extracted from microcontrollers. This simplifies the process of understanding the binary contents and thus allows you to achieve your reversing goals more efficiently. The plugin is similar to the built-in SVD loader; however, it offers a simpler data structure that could be created manually from the publicly available documentation.
Copy the firmloader.py and firmloader_data folder to the IDA plugin folder (for example: cp -R fimrloader* <IDA_FOLDER>/plugins).
Usage
Load the binary into IDA, make sure that the base address is in accordance with the documentation for the given processor, set the name of the main code segment to ROM and then use Edit > FirmLoader menu to select the MCU model. Note that this will trigger the auto-analysis of the binary.
